STEREOTYPE-CASTING APPARATUS.

SPECIFICATION forming part Of Letters Patent No. 560,395, dated May 19,1896.

` Application filed January 20, 1896; Serial No. 576,211. (No model.)

.To all whom t may concern:

Be it known that 1, CHARLES M. CoNLnY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Stereotype-CastingApparatus; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming a part of this speciiication.

This invention relates to automatically-operating means for lockingtogether the cover and matrix-bed of a stereotype-casting boxpreparatory to the casting operation and in like manner automaticallyunlocking the parts when the cast plate is about` to be removed; and thepresent improvement has for its object to provide a simple and eflicientautomatic locking means for such casting-boxes in which a uniformattachment is made at different portions of the box against springingand warping of the parts in use, and thus not only avoids the danger ofleakage of the molten metal, but also insures a perfect castplateproduct. I attain such object by the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation with partsin section of a stereotype-casting box` to which my present invention isapplied; Fig. 2, a bottom plan of the casting-box proper.

Similar numerals of reference indicate like parts in both views.

Referring to the drawings, 1 represents the main supporting-fram e,having upright standards 2, in which the casting-box is supported in apivotal manner by means of trunnions 3 on the sides of its matrix-bed 4,and rearwardly-inclined standards 5, against which the cover 6 of thecasting-box rests when the same is in an open condition.

7 is the usual stop for holding the front part of the casting-boxagainst a downward movement from its usual open and horizontal position.

8 are the usual pivoted locking-arms engaging the rear end of thecasting-box to lock the same in its horizontal open position during theremoval of the cast plate and the preparationl of the casting-box for afresh casting operation. The casting-box will consist of the usualmatrix-bed 4 and cover 6, hinged together at the rear, as shown in Fig.1.

In the present improvement, 9 are a pair of transverse locking-bars thatproject through the side walls of the matrix-bed at and have limitedmovement in elongated slots in the same; 10, a pair of longitudinal sidebars connecting the transverse locking-bars 9 together, and 11 a centralconnecting-bar that projects at the rear end of the casting-box and ispreferably provided with a bearing-roller 12 at its rear end, as shown,for the purpose hereinafter stated, the series of bars 9, 10, and 11being bolted or otherwise secured together to constitute a rigid framethat is capable of a limited reciprocation within the hollow bottom ofthe matrix-bed.

13 are springs secured to the matrix-bed and to the said frame, so thatthe tendency Will be to draw the frame i-n a backward direction. Thetension of these springs is capable of adjustment by means of screw-rods14 and adjusting-bolts 15, as shown in Fig 2.

16 are catch-plates secured to the sides of the cover portion 6 of thecasting-box by means of attaching-bolts 17 and adjustingbolts 18, andhave near their lower ends notches 19, into which the outer ends of thelocking-bars 9 are adapted to engage to lock the cover to the matrix-bedof the castingbox.

2O is a cam-plate secured to the main frame 1 and in the path of therear end of the central connecting-bar 11 and the frictionroller 12 ofthe same, the arrangement being such that when the casting-box is swunginto a horizontal position said cam-plate will engage thefriction-roller 12 to force the bar 11 forward against the tension ofthe springs 13 and cause the locking-bars 9 to move forward out ofengagement with the notches 19 of the catch-plates 16, leaving the coverfree to be swung away from the matrix-bed for the removal of the castplate and the preparation of the casting-box for a fresh castingoperation. After being so prepared the castingboX will be swung backinto a vertical position, in which to receive the molten metal. In theinitial part of this movement the friction-roller 12 leaves thecam-plate 2O and the IOO springs 13 are free to draw the locking-bars 9into engagement with the notches 19 of the catch-plates 16 to lock thecover and matrixbed together in a very firm and substantial manner.

I-Iaving thus fully described my said invention, what I claim as new,and desire to secure by Letters Patent, is-

1. In a stereotype-casting apparatus, the combination of the fixedsupporting-frame, and casting-box journaled thereon, a centrallyarrangedcam-plate secured to the frame, a reciprocating frame guided on thematrix-bed and carrying locking-bars 9, that project at each side of thematrix-bed, and a centrally-arranged and rearwardly-extending arm thatprojects into the path of the cam-plate, a series of catclrplatessecured to the cover of the casting-box, and provided with notchesadapted to engage the lockingbars, and a springtcnding to move thelocking-bars ina backward direction, substan tially as set forth.

2. In a stereotype-casting apparatus, the combination of the fixedsupporting-frame, and castingdncx journaled thereon, acentrally-arranged cain-plate secured to the frame, a reciprocatingframe guided on the matrix-bed and carrying locking-bars 9, that projectat each side of the matrix-bed, and a rearwardly-extending arm carryinga centrally-arranged friction-roller 12, that projects into the path ofthe cam-plate, a series of catch-plates secured to the cover of thecasting-box and provided with notches adapted to engage thelocking-bars, and a spring `notches 19, adapted to engage thelockingbars, and a spring for moving the locking- `bars in a backwarddirection, substantially as set forth.

4. In a stereotype-casting apparatus, the

; combination of the frame, and casting-box 1 journaled therein, acam-plate secured to the frame, a reciprocating frame sliding in thematrix-bed, and provided with lockingbars 1 9, and arearwardly-extending arm, that projects into the path of the cam-plate,a series of catch-plates secured to the cover of the casting-box, andprovided with notches adapted to engage the locking-bars, and a spring13, attached to the 1ocking-bars, and to the matrix-bed byadjusting-screw 1i, and nut 15, substantially as set forth.

In testimony whereof Witness my hand this 2d day of January, 1896.

CHARLES M. CONLEY.
